This question was not included in the 1998 HVSP FEIR. No determination was made in the 1998 HVSP FEIR regarding the significance level of impacts associated with tribal cultural resources as defined in Public Resources Code 21074 or historical resources as defined in Public Resources Code Section 5020.1(k). However, as discussed above, the 1998 HVSP FEIR included an analysis of historic and archaeological resources as defined in CEQA Appendix K Section III and determined that there would be no impact to Site CA-ALA-24. The 1998 HVSP FEIR concluded that impacts would be less than significant with implementation of MM K2, which would reduce any potential impacts to previously undiscovered historic or prehistoric resources that are encountered during construction. On January 30, 2018, FCS sent a letter to the NAHC in an effort to determine whether any sacred sites are listed on its Sacred Lands File for the project area. A response was received on March 1, 2018, confirming that the Sacred Lands File did not indicate the presence of Native American cultural resources in the immediate project area. The NAHC included a list of six tribal representatives available for consultation. To ensure that all Native American knowledge and concerns over potential Tribal Cultural Resources that may be affected by the project are addressed, a letter containing project information and requesting any additional information was sent to each tribal representative on March 6, 2018. No responses have been received to date. Tribal consultation efforts conducted by FCS did not identify additional Tribal Cultural Resources, and no Tribal Cultural Resources meeting the criteria set forth in subdivision (c) of Public Resources Code Section 5024.1. have been identified by the City of Pleasanton in its capacity as Lead Agency for the project. As such, no additional significant Tribal Cultural Resources will be adversely affected by the proposed project. Therefore, the proposed project would not result in any peculiar effects related to lead agency determined Tribal Cultural Resources and would not result in new or more severe impacts related to lead agency determined Tribal Cultural Resources beyond what was previously analyzed in the 1998 HVSP FEIR. FEIR Mitigation Measures The following site development standards and design guidelines address cultural resources of the HVSP and were adopted as mitigation measures as part of the 1998 HVSP FEIR (Appendix A). MM K2 If previously undiscovered historic or prehistoric resources are encountered during construction, work in the immediate area shall cease until such time that a qualified
